Remove the small plugs that cover the screws. There are two sizes, the ones over Big(2) have a "3" in them, see a picture in my other post.

The two big ones are feet, not screw covers.

If you are only replacing the battery or LCD you only need to remove the Big (2) and Long (2) screws.

The screw heads are very small, Phillips size 00 (PH00)

Remove the Battery Cover, lift from the top.

This will expose the battery, which can come out of the channel, but is attached with a group of wires.

Since my battery is fine, I did not look for a connector or open the covering.(Call me chicken, but I have enough problems right now)

To open the upper case there are two screws at the bottom next to the hinge/battery cover.

To be able to reach them with a screwdriver, close the lid most of the way, with the battery hanging down.

Here you can see the Strange screw head, along with the wires to the battery.

At this point I am stuck, until I find the proper screwdriver for this.

Ok Wikipeadia says it is a Tri-Wing or Triangular Slotted blade.. But as with the PH00 is it SMALLI found a small screwdriver set on ebay where they call it a Y Screwdriver. They mention other electronics,like GBA etc.

After I removed the Y Screws I was able to unsnap the lid cover.BTW those Y Screws also screw into the LCD Unit

The lid is held to the base with these arms, and these screws.The pivots have a flat cable that is wrapped around the pivot..The left one clearly has wires, the right one may not, it tore on me.Now My WiFi does not work... cause and effect? Not sure.

The LCD Unit is held down by a few of these screws and large washers.

Here we see that is it a sealed unit (LCD, Glass and Touch Screen)

And the part number LQ050W1LADA 85D16732

I thought I had another picture with the SHARP logo on the PCB, I will have to check the camera.

From what I have seen, I think the best solution for a dead LCD is finding a unit with a dead base board
